The aim of this study was to explore the relation between physical activity, sedentary behaviour, and the subjective and objective indicators of quality of life as well as life satisfaction among university students, whose education is related to different dimensions on health.
Participants (N = 595) were invited to fill in a set of suitable questionnaires. The path analysis and linear regression were used to establish a relationship between the examined constructs. Only some types of physical activity have shown a positive relation with the quality of life; the study also revealed some age and gender regularities. Physical activity in the household was most positively correlated to the quality of life. The amount of leisure and transport physical activity decreased with age, and there were also gender differences regarding the intensity and type of physical activity. Sedentary behaviour during the week related positively with the subjective quality of life and its intimacy dimension, but sedentary behaviour at the weekends was negatively related to objective and subjective quality of life as well as dimensions including intimacy, safety, and communicative aspect of the quality of life. Neither physical activity nor sedentary behaviour demonstrated a significant relation with the level of life satisfaction. The type of physical activity undertaken and its matching to the needs of the young person (in this case, a university student) affected their objective and subjective quality of life. Those findings may have important implications for institutions responsible for promoting active lifestyle.
